Media Not Showing On Wordpress Website. WPBakery Page Builder

I have a wordpress website on which there are some images and video that should be displayed. So when I go to edit the page and select the 'Single Media' widget from the WPBakery Builder and I then select an image from my library and save the page, the image does not show up on the website. The place for the image is just blank. If I inspect on that page, I get

<img src(unknown) width height alt>

This is the link to the website: https://opticoat.in/

Here's a screenshot of the inspected page: https://ibb.co/cyLjDRN
